<BR><BR>1.  Field of the Invention
<BR><BR>This invention relates to a printed circuit board holder and connector assembly.
<BR><BR>2.  Description of the Related Art
<BR><BR>Electronic enclosures are typically formed with an area to attach a connector to obtain certain signals.  A wire harness may be connected to an electronic enclosure.  The enclosure has a connector shroud that mates with a part on the wire
harness.  The connector contains metal terminals that typically have a male portion and a female portion that mate together to form an electrical path.
<BR><BR>The prior art electronic enclosures have been made by insert molding.  In insert molding, the metal terminals are placed into a plastic injection mold cavity and liquid plastic is injected at high pressure into the cavity around the metal
terminals and cooled to form the finished part.  This provides a very secure attachment between the terminals and the enclosure or housing.  Unfortunately, insert molding has many associated problems.  For example, insert molding is more expensive than
non-insert molding because additional labor is required to place the metal terminals in the mold prior to injecting the plastic.  Longer cycles times are necessary for insert molding resulting in lower production for a given machine.
<BR><BR>The injection of the plastic around the inserts can cause them to shift resulting in a defective part.  Further the shifting of the inserts can also cause damage to the mold.
<BR><BR>Connecting a printed circuit board to insert molded terminals is difficult because there is limited access to the ends of the terminals in a typical molded housing.  One solution is to use wire bonding to run a wire between the printed circuit
board and the terminals.  Unfortunately, this adds additional cost to the process.
<BR><BR>There is a current unmet need for an printed circuit board mounting system for connection with terminals in an enclosure that can be produced at a low cost and that is reliable.
<BR><BR>SUMMARY OF THE INVENTION
<BR><BR>It is a feature of the present invention to provide a printed circuit board retainer.  The printed circuit board retainer includes a plate having opposing first and second surfaces.  Several slots extend through the plate.  A latch assembly
extends from the second surface.  The latch assembly has the printed circuit board mounted to it.  Several terminals are mounted to the printed circuit board and extend through the slots.  A lock is mounted to the latch assembly to prevent the latch
assembly from releasing. <BR><BR>BRIEF DESCRIPTION OF THE DRAWINGS

<BR><BR>FIG. 2 is another perspective exploded view of a printed circuit board retainer.

<BR><BR>DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
<BR><BR>Printed Circuit Board Retainer
<BR><BR>The present invention is a printed circuit board retainer.  Referring to FIGS. 1-4 there is a printed circuit board retainer assembly 10 shown.  Assembly 10 has a plate 12 with surfaces 12A and 12B.  A connector shroud 14 extends from surface
12B.  Shroud 14 has a cavity 16 therein.  A female connector portion (not shown) would mate with shroud 14.  Several insulative walls 20 extend from surface 12A.  Walls 20 define slots 18 between walls 20.  The slots 18 extend all the way through plate
12.
<BR><BR>A latch assembly 30 is mounted between plate 12 and a printed circuit board 80.  Latch assembly 30 has a pair of rails 32 extending from surface 12B.  Rails 32 each have a pair of tabs 34.  Tabs 34 guide and hold printed circuit board 80.  A
protrusion 36 is located on the inside end of each rail 32.  Rails 32 also have a bump 38 located on the outside middle of rail 32.  A lock 50 is mounted to latch assembly 30 to prevent the latch assembly from releasing the printed circuit board 80 from
rails 32.  Lock 50 has a beam 52.  A pair of fingers 54 extend from each end of beam 52.  A hole 55 is located in each finger 54.  A lip 56 extends along one side of beam 52.  Lip 56 is designed to extend over walls 20 to cover terminals 86 after lock 50
is installed.  Lip 56 supports the terminals especially during mating with a connector to prevent the terminals from being forced out of position or to prevent overstressing the terminal to conductor pad solder joint.
<BR><BR>Printed circuit board 80 has a pair of notches 82 and several electronic components 84 mounted to board 80.  The electronic components can be almost any electronic component such as transistors, hall-effect devices, filters, resistors,
capacitors, integrated circuits.  Several terminals 86 are mounted to printed circuit board 80.  Terminals 86 have an end 86A and a curved end 86B.  Curved end 86B extends through a hole 88.  Curved end 88B would be soldered to a conductor pad 90 on
printed circuit board 80.  Terminal end 86A slides through slots 18 into cavity 16.  Walls 20 guide and support terminals 86 as they are inserted and also serve to insulate the terminals from each other.
<BR><BR>Printed circuit board retainer assembly 10 is preferably heat staked as a cover or lid to a larger enclosure or housing 9 (FIG. 3).  The enclosure would seal the printed circuit board and electronic components from environmental exposure.
<BR><BR>Assembly
<BR><BR>The printed circuit board retainer assembly 10 is assembled as follows: Terminals 86 are soldered to printed circuit board 80.  Printed circuit board 80 is slid toward plate 12.  Terminal ends 86A slide into slots 18 and extend into cavity 16. 
As printed circuit board 80 is slid, rails 32 are slightly bent outwardly by circuit board edges 81.  Tabs 34 guide circuit board 80 as is it slid.  When circuit board 80 reaches contact with plate 12, protrusions 36 slip into notches 82.  The
protrusions 36 and notches 82 hold plate 12 to circuit board 80.  Next, lock 50 is placed over rails 32.  As lock 50 is pushed over rails 32, fingers 54 are displaced outwardly by bumps 38.  As lock 50 is pushed further, bumps 38 engage holes 55 and
fingers 54 move inwardly.  Also, lip 56 now covers walls 20 and terminals 86.  The lock is now installed and prevents rails 32 from bending outwardly and inadvertently releasing printed circuit board 80 from rails 32.
<BR><BR>The printed circuit board retainer has several advantages.  It eliminates the problems associated with insert molding of the terminals resulting in a simpler lower cost manufacturing operation.  It allows for easier assembly of the terminals to
the printed circuit board because the terminals can be attached to the printed circuit board prior to assembly with the circuit board retainer.
<BR><BR>While the invention has been taught with specific reference to these embodiments, someone skilled in the art will recognize that changes can be made in form and detail without departing from the spirit and the scope of the invention.  The
described embodiments are to be considered in all respects only as illustrative and not restrictive.  The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description.  All changes which come within the
meaning and range of equivalency of the claims are to be embraced within their scope.
